[0003] This invention relates to a telemetry system enabling the transmission and analysis of data relating to aircraft flight to personnel located at a ground station.
[0004] Indicators located in the cockpit of aircraft play a significant role in the performance of flight navigation and missions by the pilot. During flight tests, a multitude of data is transmitted to the flight test management center via telemetry systems within the scope of ensuring the safe execution of the flight and performing real-time instant analyses of flight data on the ground. Telemetry system infrastructures have limited bandwidth, and the transmission of screen images within the aircraft occupies a large amount of space in the bandwidth. Therefore, it is not possible to transmit all screen images within the aircraft to the ground station simultaneously in real time. Rapid downlinking and analysis of test measurement data within the aircraft to the ground station are crucial for mitigating risks regarding the flight activities of the aircraft.
[0005] In the United States patent document numbered US2013063435A1 located in the prior art, a system and method enabling the simulation of a terrain view from the perspective of an aircraft are disclosed. In the subject system, a similar simulated image is generated at ground level by a ground-based visualization facility using the same geo-referenced terrain model and the same information generating the simulated image on the cockpit display. Thus, the personnel on the ground can see in real time on the ground display what is shown to the pilot on the cockpit display. A ground-based display displaying a view corresponding to the view displayed on the cockpit display is provided to the ground personnel to interact with the aircrew and to provide training and advice based on the simulated view.

[0043] 103. checking (103) whether the synchronization marker (Q) coming with the sub-message (S) is the same as the synchronization marker (Q) of the preceding sub-message (S) in the case that the checksum value (C) of the telemetry packet (T) is checked and the telemetry packet (T) passes the check,
[0044] 104. combining (104) the sub-messages (S) if the synchronization marker (Q) located in the two sub-messages (S) within the telemetry packet (T) is different from the synchronization marker (Q) of the two sub-messages (S) in the previously transmitted telemetry packet (T),
[0045] 105. rendering the telemetry packet (T) meaningful (105) by combining the sub-messages (S) in the case that the sequence numbers (N) of the sub-messages (S) are consecutive,

[0047] The telemetry system (1) comprises at least one aircraft (2), at least one flight data (F) containing data regarding the flight of the aircraft (2), at least one telemetry packet (T) containing a plurality of flight data (F) having features regarding the flight of the aircraft (2), at least one air controller (3) located within the aircraft (2) and enabling the conversion of theflight data (F) into a format viewable by the user, at least one vehicle display (4) located within the aircraft (2) in data exchange with the air controller (3) and enabling the pilot to view the flight data (F), at least one telemetry controller (5) enabling the conversion of the flight data (F) located in the telemetry packet (T) transmitted by the air controller (3) into a format viewable by the telemetry operator, and at least one ground display (6) communicating with the telemetry controller (5) and enabling the telemetry operator to view the flight data (F). (Figure 1)
[0048] It comprises a telemetry controller (5) processing the telemetry packet (T) and determining and eliminating erroneous and / or repetitive flight data (F), processing and analyzing the telemetry packet (T) via prediction algorithms determined by the user, generating failure predictions regarding the aircraft (2) as a result of the analysis, generating warnings regarding the failure predictions and transmitting them to the ground display (6) thereby enabling the telemetry operator to view them, and enabling the flight data (F) other than the flight data (F) instantly viewed by the pilot on the vehicle display (4) to be selected and viewed by the telemetry operator on the ground display (6).
[0049] There are provided an aircraft (2), flight data (F) containing information regarding the flight of the aircraft (2), and a telemetry packet (T) carrying the flight data (F) therein. An air controller converting the flight data (F) into a format viewable by the pilot is located within the aircraft (2). The visualized flight data (F) are transmitted to the pilot via the vehicle display (4). The flight data (F) carried in the telemetry packet (T) transmitted by the air controller (3) are converted into a format viewable by the telemetry operator by the telemetry controller (5). The ground display (6) communicates with the telemetry controller (5) and enables the telemetry personnel to view the visualized version of the flight data (F).
[0050] The telemetry controller (5) processes the telemetry packet (T) and eliminates the erroneous / repetitive data in the case that erroneous and / or repetitive data exists within the flight data (F). The telemetry controller (5) processes and analyzes the telemetry packet (T) using prediction algorithms predetermined by the user.

Thanks to the telemetry controller (5), it is made possible for the telemetry operator to monitor and control the flight data (F) instantly viewed by the pilot on the vehicle display (4) and the flight data (F) not viewed at that moment. In this way, raw flight data (F) collected within the aircraft (2) is transmitted to the telemetry controller (5) located at the ground station, and the data to be displayed on the vehicle display (4) is separated from the other flight data (F).

In this way, it is ensured that the flight data carried in the telemetry packet (T) is transported safely and without errors.

In this way, the flight data (F) not fitting into the telemetry packet (T) is placed to be carried within a sub-message (S) in the next telemetry packet (T). Thus, different sub-messages (S) are carried in such a way that no empty space remains within the telemetry packets (T), and efficiency is increased.

[0055] • combining the sub-messages (S) if the synchronization marker (Q) located in the two sub-messages (S) within the telemetry packet (T) is different from the synchronization marker (Q) of the two sub-messages (S) in the previously transmitted telemetry packet (T) (104),

[0057] • not combining the sub-messages (S) in the case that the number of sub-messages (S) within the telemetry packet (T) is greater than determined by the ground operator and / or the sequence number (N) is not consecutive (106).

In this way, correlations and analyses regarding the flight data (F) are obtained.
[0060] In an embodiment of the invention, the telemetry system (1) comprises a telemetry controller (5) processing the outputs (O) with artificial intelligence-based algorithms determined by the ground operator and performing classification regarding the outputs (O), thereby generating a warning by detecting an error and / or incompatibility situation determined according to predetermined threshold values in the flight data (F), transmitting the generated warning to the vehicle display (4), and enabling the pilot to view the warning on the vehicle display (4).
